Wolff: Conway, Spicer, Hicks all helped get interviews for my book

Michael Wolff, the author of the new White House tell-all "Fire and Fury", said Monday both current and former top White House officials encouraged other aides "to cooperate" in interviews for the book.

"Everybody was told to speak to me," Wolff said in an excerpt from his interview set to air in full on CNN's "Tonight with Don Lemon." 

"[Stephen] Bannon told people to cooperate, Sean SpicerSean Michael SpicerSpicer: CNN 'doing a disservice' by boycotting White House Christmas party DNC attorneys allowed to depose Spicer over election night presence in Trump Tower Sean Spicer to judge DC dance-off MORE told people to cooperate, Kellyanne ConwayKellyanne Elizabeth ConwayaOffice opens case file into accusation that Conway broke the law Conway: North Korea's Kim Jong Un insulted Trump first Conway: 'Rush' to politicize Texas shooting is 'disrespectful to the dead' MORE told people to cooperate, Hope HicksHope Charlotte HicksTrump campaign staffer: Hope Hicks ‘loves Trump like a father’ Mercedes Schlapp joins White House as senior communications adviser Hope Hicks named Trump’s third White House communications director MORE," he said respectively about the president's former chief strategist, former press secretary, senior adviser and current communications director.

Wolff said he conducted over 200 interviews for his new book, "Fire and Fury: Inside the Trump White House," which paints President Trump as an unstable leader leading a White House in chaos.

“Why are they saying its fake?” Lemon asks.

“Because they are liars," Wolff responds. 

"He doesn’t tell the truth because he doesn’t know what the truth is."

Conway, Hicks and Spicer did not immediately respond to individual requests to comment on Wolff's remark.

Wolff claims in his book that "every single" person around Trump questions "his intelligence and fitness for office."

Trump has repeatedly blasted book as "full of lies." Other White House officials have fiercely pushed back on the claims, while others have raised their eyes about some of Wolff's broad statements.

Wolff acknowledges in the book’s introduction that certain parts of the book reflect “a version of events I believe to be true" but that are sometimes based on conflicting accounts.

Many of the bombshells in the book come from quotes by Bannon, Trump's former White House chief strategist's 

The book quotes Bannon blasting Donald Trump Jr., calling him "treasonous" and "unpatriotic" for attending the now infamous June 2016 Trump Tower meeting with a Russian lawyer.

Bannon, who also made disparaging remarks about Ivanka TrumpIvana (Ivanka) Marie TrumpTrump frustrated with Ivanka's condemnation of Roy Moore: report Ivanka, do the right thing: Endorse Doug Jones over Roy Moore Ivanka Trump: Sexual harassment 'can never be tolerated' MORE and Jared KushnerJared Corey KushnerKushner: Trump team working on Mideast peace plan unconventional, but ‘perfectly qualified’ US attorney fired by Trump: Mueller team likely looking at everyone Additional Trump transition official identified who knew about Flynn's Russia contact: report MORE, later only walked back his remarks about the president's eldest son and said those comments were directed towards former campaign chairman Paul ManafortPaul John ManafortJudge warns Manafort not to discuss case with media Manafort involved in drafting op-ed defending his Ukrainian work: court papers Trump went off on Manafort for suggesting he should not appear on Sunday shows: report MORE.

The White House, however, rejected Bannon's statement of "regret."
